Process of making a seal and apparatus for sealing doublewide manufactured homes |
摘要 |
A process for making a sealing material for sealing doublewide manufactured homes includes the steps of selecting an elongated seal core made of a foamed polymer and selecting a flexible polymer covering sleeve for loosely covering the selected seal core and covering the seal core with a loose fitting covering sleeve. The covering sleeve is then shaped to form a skin over the seal core by forming a pair of flanges from the slack material in the covering sleeve with a folded portion of the covering sleeve and attaching the folded portions together to form flanges. A seal for a doublewide manufactured home is formed by the process and has an elongated polymer foam core covered by an elongated flexible polymer sleeve and having a pair of elongated flanges formed with folded slack material in the flexible polymer sleeve which folded flange portions are attached together, such as by sewing. A predetermined density foam core material of a larger size is covered with a woven polypropylene material.
